Please understand that the purpose of our review process is to assist you in your compliance with the applicable disclosure requirements and to enhance the overall disclosure in your filing. We look forward to working with you in these respects. We welcome any questions you may have about our comments or on any other aspect of our review. Feel free to call us at the telephone numbers listed at the end of this letter. Form 10-K for the year ended December 31, 2004 Financial Statements Notes to Consolidated Financial Statements, page 47 Note 1: Summary of Operations and Significant Accounting Policies, page 47 l.

Tell us and disclose in future filings the significant terms of these arrangements with distributors, including any post shipment obligations, acceptance provisions and return provisions that may exist and how you account for such obligations. Also, tell us supplementally if you grant price concessions to your distributions and if so, tell us how you account for price concessions. Please expand your policy for revenue recognition to include the accounting for distributor arrangements in future filings to the extent sales through distributors are significant. 2. Reference is made to your disclosure on page 9 stating that you have traditionally had a number of long-term sales contracts with customers." Expand in future filings to disclose the nature and terms of such contracts. Note 6: Commitments and Contingencies, page 56 e. Government Grants/Loans, page 57 3. It appears from your disclosure that you obtain certain grants/loans from government agencies to assist with various funding needs. Clarify to us how you account for funding received under these programs. Also, we note in September 2003 you entered into a contract with CECOM and received $3.1 million for manufacturing equipment to expand capabilities. Tell us how you will account for the receipts and expenditures in connection with this contract. Note 8: Income Taxes, page 62 4. We note that you substantively reduced your valuation allowance for deferred tax assets related to US operations in 2004 primarily as a result of current year earnings and your expectation of future profitability from US operations. Tell us and revise here and in MD&A in future filings to provide an enhanced discussion of the reasons why you believe at this time that realization of the deferred tax assets is more likely than not given your lack of history of profitability. Refer to the guidance provided in paragraphs 20-25 of SFAS 109. 5. Supplementally tell us in further detail the nature of the "change in ownership" that took place in the fourth quarter 2003.
